Level 5 - mechanism / opinion, no new human data
Narrative review of physiological mechanisms without systematic review methodology or new human trial data.

What was done
Narrative review evaluating the physiological mechanisms and potential utility of post-exercise water immersion (including cool to thermoneutral temperatures) to enhance recovery in athletes during repeated exercise bouts.
What was found
The abstract reports no numerical data. It notes theoretical physiological mechanisms including intracellular-to-intravascular fluid shifts, decreased muscle edema, and increased cardiac output (without increased energy expenditure) leading to increased blood flow and waste transport, alongside possible psychological reductions in perceived fatigue.
Why it matters
It outlines the proposed biological mechanisms underlying post-exercise hydrotherapy while highlighting a gap between popular anecdotal adoption and objective performance evidence.
Limits
As a narrative review, it lacks systematic search criteria, quality appraisal, and meta-analytic pooling. No primary empirical performance data or quantitative effect estimates are presented.
